"Praise God in His sanctuary" (Psalm 150:1). "Your body is the temple of the Holy Spirit... glorify God in your body, and in your spirit, which are God's" (1 Corinthians 6:19-20).
Where does praise come from? How do we learn to "glorify God"? We learn that we "have been bought with a price" (1 Corinthians 6:20). At the Cross of Christ, we learn to praise God. We see Jesus, crucified for us - and our hearts are filled with praise to God. This is where praise begins. It doesn't begin with us. It begins with God. It begins with Jesus. It begins with the Holy Spirit.
